[QUOTE="aaroncarp, post: 979629, member: 80044"] I have spent some time this summer on here asking for advice to develop a mag fit load for my 300 RUM that shoots well. Finally found one the other day (210VLD, 92 grains of retumbo, 3.675" OAL) Anyways, I have a couple of questions because the day that the load shot about a half inch it was probably 75 or 80 degrees out. I gave the barrel 5 to 10 minutes for cooling between shots and what not. 1. Will I see much difference in grouping when Im hunting below 40 degrees? 2. Should I wait until it cools off to shoot it through a chronograph? I have heard that retumbo is very temperature stable, but I am not sure. Thanks [/QUOTE]
